VRF systems for a modern and complex architecture
The City Multi series is ideal for large and complex buildings that require individual solutions for air conditioning. The diversity of the indoor units and the wide range of outdoor unit capacities ensure the highest level of flexibility in terms of planning and design. These advanced VRF systems are characterised by superlative energy efficiency values and extremely high reliability, ensuring optimal climate comfort, for instance in offices, shopping centres, hotels, hospitals and public buildings.

Extending the technology edge - the new series of VRF systems:
With improved basic functions, state-of-the-art compressor and optimised fan – in short, all the features you need to save energy!

New City-Multi unit
The new structural design works with a four-way air intake system and improved core components (e.g. compressor and fan). This significantly improves the energy-saving performance.

New design
With its elegant design, the new unit harmonises with any architectural style and blends discreetly into its surroundings.

High energy savings
Many of the core components have been redesigned to increase energy-saving performance and meet customer requirements. And the results are impressive: Not only is energy efficiency higher than with a conventional (YLM) model, but top-class energy saving performance has been achieved. The SEER value (seasonal energy efficiency) of the YNW series has been improved by up to 33% (Y: EP350; compared to conventional models), while the SCOP was improved by almost 19%. (Y: EP500). And this means year-round energy savings – both in heating and cooling mode.

Variable low-noise mode
The standard low-noise mode, which previously had only a single setting, now has four setting options. Including the rated fan speed, this means that five settings can now be selected on the outdoor unit via the DIP switches. Low-noise mode offers four fan speeds: 85%, 70%, 60% and 50% of the rated speed. When low-noise operation is required, the appropriate level can be selected according to customer requirements.

Four-way air intake system
In conventional models, a U-shaped heat exchanger is mounted along the side surface. In the new model, the four-way heat exchanger is located in the upper part of the module, near the fan.
This enables the air to be sucked in at a high intake rate and the efficiency of the heat exchanger to be increased.

Efficient flat-tube heat exchanger
In addition to conventional round-tube heat exchangers, flat-tube models are now also available. The advantage of this is that when using flat tubes, the number of tube stages can be increased without changing the dimensions of the heat exchanger. Inside the tube are thin-walled chambers, which serve to increase the contact surface between refrigerant and air. This raises the efficiency of the heat exchange process and significantly improves energy-saving performance. Compared to the round-tube model, flat-tube heat exchangers increase the heat exchange efficiency by approx. 30%.
